RUBIN, OF WINNIPEG, MANITOBA, CANADA, ASSIGNOR TO IDA WILENSKY, OF DEVILS LAKE, NORTH DAKOTA BOX-SPRING MATTRESS Application filed February 24, 1926, Serial No. 90,230, and in Canada January 26, 1926.

The invention relates to improvements in box spring mattresses and an object of the invention is to provide what is known to the trade as a box spring mattress but in which the customary weight supporting helical springs have been dispensed with and a spring wire fabric substituted, the fabric giving me a non-sagging spring and also dispensing with the many incident troubles experienced where helical springs are employed.

A further object of the invention is to provide a box spring mattress which can be manufactured at comparatively small cost and which can be easily and quickly assembled and which is amplyreinforced at the edges and which retains the general appearance of the ordinary box spring mattress now on the market.

With the above more important and other minor objects in view which will become more apparent as the description proceeds, the invention consists essentially in the arrange ment and construction of parts, hereinafter more particularly described, reference being had to the accompanying drawings, in which Fig. 1 is a vertical longitudinal sectional view centrally through my box spring mattress.

Fig. 2 is a vertical cross sectional view centrally through the box spring mattress.

Fig. 3 is a perspective view of one of the corners thereof with the upper covering removed.

Fig. 4 is a perspective view of the corner bracket employed.

Fig. 5 is a perspective view of a portion of the spring filling used.

In the drawings like characters of reference indicate corresponding parts in the several figures.

The main frame of the mattress is substantially rectangular and embodies similar side rails 1 and 2 of angle iron cross section and head and foot rails 3 and 4 also of angle iron cross section, these rails being permanently riveted at the ends to corner brackets 5.

Four corner brackets are employed and referring to Figure 4, it will be observed that each corner bracket is provided with a socket 6, below the socket with an outstanding suitably reinforced lug 7 and at the top with a suitably reinforced horizontal lug 8 and two corner lugs 9 and 10 disposed ninety degrees apart, there being a hole reserved at 11 for a purpose later described. Further it will be noted that the lower end of the bracket presents a seat 12 and a downwardly extending stop 13 forming a right-angled shoulder 14 with the seat.

The side rails 1 and 2 are permanently secured as by riveting to the lugs 7 and the head and foot rails 3 and 4 are permanently fastened by rivets 15 to the bodies of the brackets, it being here observed that the outer faces of the brackets are countersunk as indicated at 16 to receive the vertical webs of the head and foot rails. Similar side tubes or pipes 17 and 18 are also provided, these having their ends received within the sock ets 6. These tubes materially strengthen the frame. I provide also upper head and foot rails 19 and 20 also of angle iron cross section which have their ends fastened permanently by rivets 21 to lateral extensions 22 of the brackets.

The frame above described is a rigid structure and is amply reinforced against the various strains imposed thereon by the tubes 17 and 18 and the cross rails 19 and 20.

It will be observed that the lugs 8 at the head and foot of the frame are in the same horizontal plane as the upper edges of the vertical flanges of the rails 19 and 20. The vertical flanges of the elevated end rails 19 and 20 are provided with suitably spaced holes 23 adjacent their upper edges and the lugs 8 are also provided with spaced holes 24, these latter holes being quite close together. Similar horizontally disposed coiled springs 25, having hooked ends, are caught in the eyes provided by the holes 23 and 24.

The springs are all connected together by wires 26, these wires being woven alternately backwardly and forwardly and being caught on the inner hooks of the springs. I find it desirable to use separate wires for connecting the outer springs or those caught in caught in the hole and by utilizing a suitable tool, it is an easy matter to pull the outer hooks of the springs endwise and catch them in the proper holes one after another. After the wire fabric has been'tightened up in the manner just explained, the adjacent strands of the wires are caught together by suitably positioned hooked clips 27.

The lugs 9 and 10 of the brackets are also provided with holes 28 and 29 and. in these holes, I catch the hooked ends of further pairs of side and end horizontally disposed, coiled springs 30 and .31 and the side springs are connected by side wires 32 and the end springs by end wires 33, these wires being woven backwardly and forwardly and caught on hooks supplied at the inner ends of the said springs. These latter wires amply reinforce the edges of the mattress as later explained.

In order to avoid any undue sagging of the wire fabric above described, I have provided an underlying fabric indicated generally by the reference numeral 34, this fabric comprising horizontally disposed coiled springs 35 connected by wires 36 and put together in the same manner as the upper fabric, the outer ends of the springs 35 being caught in suitable spaced holes 37 provided in the in ner edges of the horizontal flanges of the end rails 19 and 20. Obviously if a heavy person be lying 'on the mattress, the upper fabric will spring down until it engages the under fabric and then the two fabrics will 'act to support the load imposed without undue sagging. Obviously the under fabric could'be dispensed with by a manufacturer if he so desired.

I might here mention also that the wire which I utilize in the making of the fabric is in the form of wire strands spirally wound in a tubular manner so that there is a hollow core therein. Such wire is now manufactured. I

A covering generally indicated by the ref erence numeral 38 is placed over the upper wire fabric to cover the same. In the present instance, this covering is shown as a lower canvas strip 39, an upper ticking strip 40, an intervening spring filling 41 and a padding of cotton batting or such like 42 between the ticking and the spring filling.

The spring filling employed is at present commercially manufactured and embodies cylindrical-like cloth casings 43 containing comparatively light vertically disposed spring coils 44 'and the several casings forming the cylindersare suitably tied together. The edges and ends of the ticking and the canvas strips are brought together at the sides and ends of the frame and passed downward- 1y over the outer faces of the side and end rails and are then turned under the horizontal flanges of the rails 1, 2, 3 and 4 and fastened by tacks or such like 45 to wood strips 46 suitably secured to the horizontal flanges of the latter rails. In this way, 1 form comparatively deep side and end walls to the mattress and at the points where the side walls meet the covering, I form rolled edges 47 which are also stufied with cotton batting 48 and which contain the side and end wires 32 and 33. The rolled edge is formed by looping, so to speak, the ticking around thelatter wires, filling with the cotton batting and then cross stitching as indicated at 49.

By the above arrangement, I give the completed mattress a natural finished appearance and the edges and ends thereof are amply reinforced by the wires contained within the rolled edges aforesaid.

Whilst I have shown the covering as containingthe well known spring filling, I wish it to be understood that this springfilling can be entirely dispensed with and the hollow a.

space between the ticking and the canvas filled with the cotton batting or such like 42 and without departing from the spirit ofthe invention.

Obviously this box spring mattress is;

strongly constructed, will not sag in the centre and has the same exterior appearance as the many other well known box spring mattresses now on the market and it is so designedthat the weight of those reclining'on-itis sup-" ported by a woven wire fabric instead of by a plurality of vertically disposed coiled springs as customarily employed and in this connection I might remark that whilst thesprings 44 are vertically disposed, coiled springs, they are not intended to carry the load'but-simply as a cushioning means embodied in the'cover which actually might be. made without using these latter springs and without'departing from the spirit of the invention.

The holes 11 are provided to permit-of the easy end pulling of the springs 25, the hooked tool provided for pulling these springs being passed through the said openings.

The parts 12 of' the corner brackets are adapted to rest on the side rails of the customary bedstead and the right angled shoulders 14 prevent lateral shifting of the box spring frame on the side rails of the bedstead.

WVhat I claim as my invention is 1. A box spring mattress comprising a substantially rectangular under frame embodying lower side and end rails and corner brackets connecting said rails and extending upwardly therefrom, reinforcing tubes extending between the corner brackets and located above the side rails, elevated head and foot rails secured to and extending between the corner brackets, an upper woven wire fabric carried by the elevated head and foot rails, a further woven Wire fabric carried by the latter rails and underlying the former fabric, a covering overlying the upper fabric and having the sides and ends thereof extended into flaps the lower edges of which are fastened to the side and foot rails of the under frame and reinforcing wires concealed in the ends and edges of the covering and extending between the corner brackets.

2. In a bed spring construction, a substantially rectangular sub-frame, upstanding corner brackets located at the corners of the frame, elevated head and foot rails extending transversely between the corner brackets and presenting vertically and horizontally disposed flanges, an upper tensioned woven wire fabric carried by the vertical flanges of the head rails, a further tensioned woven wire fabric underlying the former fabric and carried by the horizontal flanges of the head rails and compression tubes extending longitudinally of the sub-frame and having their ends attached to the brackets, said tubes being positioned intermediately between the subframe and the fabrics.
